Jaw Pullers

A jaw puller is a mechanical tool designed to grip and extract parts such as bearings, gears, pulleys, and steering components from shafts or housings by applying even pulling force through adjustable jaws and a central forcing screw

Select a puller whose reach and jaw spread accommodate the part diameter and depth; two- and three-jaw models are common—three-jaw pullers provide centered, balanced grip for round parts, while two-jaw or internally converted jaws suit narrow or internal pulls; check maximum pulling capacity and jaw thickness for clearance

Look for heat-treated alloy steel or forged components for the jaws and forcing screw, corrosion-resistant finishes like black oxide, and replaceable tips or sleeves; these features resist bending, galling, and wear under repeated high torque

Wear eye protection, ensure the puller is centered and jaws are fully engaged, use gradual, controlled torque (preferably with a breaker bar and socket designed for the forcing screw), and consider using pulling adapters, protective jaw pads, or penetrating oil to reduce risk of part breakage and sudden release

Jaw pullers typically range from budget options under $50 to higher-capacity or specialty sets over $100; price varies with material quality, maximum pulling capacity, number of components in a set, and included adapters or carrying cases

Damage can occur from misalignment, using excessive force, or metal-to-metal contact; avoid damage by centering the forcing screw, using protective jaw covers or blocks, applying penetrating oil, and switching to appropriate internal/external jaw configurations for the part

Keep the forcing screw lightly lubricated, clean debris from threads and jaw surfaces after use, inspect for bending or thread wear, replace worn tips, and store the tool in a dry case or toolbox to prevent corrosion
